TeX4ht – Convert (La)TeX to HTML/XML

A con­verter from TeX and LaTeX to SGML-based for­mats such
as (X)HTML, MathML, OpenDoc­u­ment, and DocBook, pro­vid­ing a
con­fig­urable (La)TeX-based au­thor­ing sys­tem for hy­per­text.

TeX4ht does not parse (La)TeX source (so that it avoids the
dif­fi­cul­ties en­coun­tered by many other con­vert­ers, aris­ing from
the ir­reg­u­lar­ity of (La)TeX syn­tax). In­stead, TeX4ht uses (La)TeX
it­self (with an ex­tra macro pack­age) to pro­duce a non-stan­dard DVI
file that it can then pro­cess. This tech­nique al­lows TeX4ht to
ap­proach the ro­bust­ness char­ac­ter­is­tic of re­stricted-syn­tax
sys­tems such as hy­per­la­tex and
gellmu.

Note that CTAN no longer holds the defini­tive sources of the
pack­age: see the ‘Readme’ file.
